The volts wont be exact but in the ball park. EX is the G-2's can adjust
between 250 V & 800 V. if off by 20% thats OK. Looking for BIG diference.
The 1974 jug is probably a 25" viewable, the old one probably 23" viewable
so wont swap. Also about 1974 Sylvania CRT's only lasted a few yrs.
IIRC they were called "GT-Matics" & the main chassis was 3 large modules & the CRT was called "Dark Light".

OK Thanks for the info. So it sounds like the Sylvania Pix Tubes from the 1960s were actually better than the ones from the 1970s? Am I understanding correctly?

Also I'm hoping that the red gun testing dead on my tube tester is just a matter of a malfunction in the tube tester itself and that the picture tube is actually still good and that the poor pix performance is just a matter of some sort of malfunction in the color demod circuitry (like a bad capacitor or two and or a bad transistor or two) Because this TV is a really good performer otherwise and has a really good performing tuner section.
